Subject: Clear saved input focus if the widget is removed from the container
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=ab45b7660aec83978871ade009846dcb8c34579f;hp=ab45b7660aec83978871ade009846dcb8c34579f;p=libs%2Fgltk.git

Clear saved input focus if the widget is removed from the container

Checking the saved focus widget's parent in focus_in can lead to use
after free if the widget was deleted in the meantime.
